... SOT-223 package. The MIC39101 and MIC39102 are fixed and adjustable regulators, respectively thermally en- hanced power 8-lead SOP (small outline package). The MIC39100/1/2 is ideal for PC add-in cards that need to convert from standard 5V to 3.3V, 3.3V to 2.5V or 2.5V to 1.8V. A guaranteed maximum dropout voltage of 630mV over all operating conditions allows the MIC39100/1/2 to provide 2 ...

... To convert down to 2.5V or 1.8V without operating in dropout, NPN- based regulators require an input voltage of 3.7V at the very least. The MIC39100 regulator will provide excellent perfor- mance with an input as low as 3.0V or 2.5V respectively. This gives the PNP based regulators a distinct advantage over older, NPN based linear regulators ...
